Fair enough, there are trade secrets and intellectual property issues here (although there are ways of sorting that too - tones, step forward  ), but certainly in my field the vast majority of significant research in the industrial sector gets published eventually in one form or another - it's an essential part of maintaining scientific credibility and of course helps move the cutting edge forwards (especially if you're sitting on something genuinely new). At the moment though all you'd really need to publish would be your test setup and the results reported by your subjects and IMO at least you'd already be light-years ahead of any of your competitors in terms of credibility.
